Description
Technical field
The present invention relates to Kiwi berry planting technology field, more particularly to a kind of Kiwi berry transplant planting Special slow release fertilizer.
Background technology
Kiwi berry nickname Chinese gooseberry, carambola or Mao Muguo etc., elliptical in its outer shape, epidermis are dark brown and with hair, are in it
In the pulp of bright green and the black seeds at center, above-mentioned pulp is soft, and taste is commonly described as strawberry, banana, pineapple three
Combination, in addition, the nutriment needed in pulp rich in the various human bodies such as vitamin C, amino acid, mineral matter, claimed
It is very popular for " king of fruit ".
In the planting process of Kiwi berry, need initial stage to apply enough base manure in the ground, to meet that Kiwi berry fruit tree gives birth to
Nutrition required for long early stage, later each stage need top dressing to meet the growth needs of different time fruit tree, in macaque
It is big to the demand of fertilizer in the growth course of peach, in addition to nitrogen, phosphorus, potassium is needed, it is also necessary to the member such as abundant magnesium, manganese, zinc, iron
Element, if lacking these mineral elements in soil, malnourished nutritional deficiency disease is often shown on blade.
Grower often only payes attention to improving the yield of Kiwi berry at present, repeatedly using the incomplete chemical fertilizer of nutriment, leads
Kiwi berry is caused to lack sufficient nutrient, it is low fertilizer absorption rate occur, the slow phenomenon of Kiwi growth, does not reach high yield effect
Fruit, and quality of Chinese gooseberries is poor, and environmental pollution is caused while reducing economic benefit.
The content of the invention
The present invention proposes a kind of Kiwi berry transplant planting Special slow release fertilizer, and it is disease-resistant that the present invention can strengthen kiwi fruit plant
Ability, early ageing is prevented, promote fruit growth uniform, reduce the generation of malformed fruit, promote fruit appearance bright in color, improve production
Amount, increase the accumulation of Kiwi berry sugar, improve the quality of Kiwi berry.
The present invention proposes a kind of Kiwi berry transplant planting Special slow release fertilizer, and its raw material includes by weight:Coated carbamide
70-80 parts, calcium superphosphate 30-50 parts, MAP 10-22 parts, potassium chloride 4-12 parts, calcium nitrate 0.1-0.4 parts, magnesium sulfate

Preferably, in coated carbamide, fusing urea, chitosan, boric acid are mixed, in 75-82 DEG C of stirring of temperature, added
Maleic anhydride, microcrystalline cellulose, isopropanol, water are well mixed, and add sulfuric acid solution, in 80-90 DEG C of stirring in water bath of temperature, regulation
For system in neutrality, decompression boils off water and isopropanol, and cooling obtains coated carbamide.
Preferably, the concentration of sulfuric acid solution is 1.5-2.5mol/L.
Preferably, fusing urea, chitosan, the weight ratio of boric acid are 5-15:20-28:5-14.
Preferably, maleic anhydride, microcrystalline cellulose, the weight ratio of isopropanol are 0.2-0.8:1-2:20-30.
Preferably, coated carbamide, calcium superphosphate, MAP, the weight ratio of potassium chloride are 72-76:40-46:12-15:
6-8。
Preferably, in fermentation poultry dung, fermented using EM bacterium solutions, the weight ratio of wherein chicken manure and EM bacterium solutions is 100:1-2.
Preferably, effective bacterial content is 1.2-1.6 × 10 in the EM bacterium solutions9CFU/ml。
Preferably, in the preparation process of fermentation poultry dung, it is sealed by fermentation, fermentation temperature is 40-46 DEG C, fermentation time 1-
2 days.
Preferably, in fermentation poultry dung, 40-60 parts wheat bran, 1-2 part EM bacterium solutions are well mixed by weight, room temperature is close
Seal ferment 2-4 days, add 100 parts of chicken manures and stir, it is 50-60wt% to add water to water content, in 40-46 DEG C of sealing hair of temperature
Ferment 1-2 days, during which turning once, obtain fermentation poultry dung.
The present invention can carry out soil improvement, the sugariness of the sugariness of gained Kiwi berry compared with import Kiwi berry to Kiwi berry planting site
Height, sugariness can reach 18, and fertilizer can be fully absorbed by Kiwi berry, after the slow release fertilizer, the sugar content of Kiwi berry
10-18%, delicate mouthfeel are added compared to conventional fertilizers, selling price is higher than the fruit of traditional planting patterns, adds kind
The income at family is planted, more nutrition are provided for eater.
In the coated carbamide of slow-release fertilizer, fusing urea, chitosan, boric acid react under certain condition, the hydroxyl of chitosan
Base and boric acid are complexed and are grafted on urea, can suppress the activity of soil urease, improve the utilization rate of urea, and microcrystalline cellulose
Above-mentioned pretreatment urea surface is coated after being grafted with maleic anhydride, adhesion strength is high, further coordinates abienol blending, can be to urine
Element is sustained, antioxidant effect, and compatibility is good between unclassified stores, had good sustained release effect.
Slow-release fertilizer is compounded using coated carbamide and calcium superphosphate, MAP, potassium chloride, is Kiwi berry main N, P, K
Source, coordinate zeolite powder, flyash, fermentation poultry dung effect, can effectively prevent the hardened of soil, soil permeability is good, and water conservation is protected
Fertile ability is strong, and survivable environment can be provided for beneficial bacterium, can effectively maintain nutriment necessary to Kiwi growth, together
When improve soil, promote the growth of Kiwi berry, add the yield of Kiwi berry, improve soluble solid in Kiwi berry
The content of thing, vitamin C etc., improves the quality of Kiwi berry, and the soluble solid of Kiwi berry is up to 17.6%, sugar content and
Sugar-acid ratio is also high, and sugar-acid ratio is up to 14.5, excellent taste.
